GeneralGeneralGeneralGeneral The 74VHC273FT is an advanced high speed CMOS OCTAL D-TYPE FLIP FLOP fabricated with silicon gate C2MOS technology. It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. Information signals applied to D inputs are transferred to the Q outputs on the positive going edge of the clock pulse. When the CLR input is held, the Q outputs are at a low logic level independent of the other inputs. An input protection circuit ensures that 0 to 5.5 V can be applied to the input pins without regard to the supply voltage.This device can be used to interface 5 V to 3 V systems and two supply systems such as battery back up. This circuit prevents device destruction due to mismatched supply and input voltages. 3. 3. FeaturesFeatures 3. 3. FeaturesFeatures (1) AEC-Q100 (Rev.
